Built because fleets asked

Winners has been on this Telegraph Road location since 2007, and serving Downriver far longer. Retail and fleet customers told us the same thing: light and medium duty diesel was underserved. Winners Diesel Services exists as a separate specialty shop because of that demand. Quality diesel repair, on time, at a fair price. Fleet and diesel programs are the rising work here.

What a fleet account looks like

  • Priority on the board. Preferred status so a down truck is not waiting behind walk-ins.
  • Direct communication. Diagnosis first. No parts-cannon, no “we will know when we know.”
  • PM that matches the route. Oil, filters, DEF, cooling, and inspections cycled so you are not surprised on a Monday.
  • The engines you actually own. Powerstroke, Duramax, Cummins — stock or modified.

Call (734) 229-1017 and ask for fleet scheduling, or send the truck list.

Fleet work we handle

  • Fleet preventive maintenance

    Scheduled oil, filters, DEF, inspections, and PM so your trucks stay on the route instead of in a bay.

  • Diesel diagnostics

    We diagnose light and medium duty electronics correctly — the broken wire, the fuel issue, the no-start — before anyone orders a pile of parts.

  • Engine repair & overhaul

    From a no-start to a complete overhaul on Powerstroke, Duramax, and Cummins. Fair price, no guesswork.

  • Fuel system service

    Injectors, pumps, contamination, and Duramax transfer-pump issues on light and medium duty GM trucks.

  • Emissions & aftertreatment

    DPF, EGR, and related drivability on modern light and medium duty diesels — repaired so they stay in service.

  • Drivability & electrical

    Intermittents, wiring, sensors, and the complex electrical systems that keep fleets off the road.

Who this shop is for

Contractors & trades

Dump-bed F-250s, service bodies, and the Duramax that tows the equipment trailer every morning.

Municipal & utility

Light and medium duty chassis that have to be back on the job.

Delivery & service companies

Diesel vans and pickups that only make money when they are moving.

Owner-operators with a small yard

Two to twenty trucks. You still get a real conversation, not a fleet portal.
